In Tao the only motion is returning;
The only useful quality, weakness.
For though all creatures under heaven are the products of Being,
Being itself is the product of Not-being.
This chapter (40) of the Dao De Jing is a classic statement of emptiness, the via negativa, which means God, the source of all existence, is a darkness to the intellect and a Being devoid of all the attributes that characterise our physical reality.
Return, reversal, weakness, softness, meekness: these human attributes are our way of coming to know Him and trust in His power.
Being is you 有 meaning “have”, not-being is wu 無 meaning “without”.
In Christianity and other systems we are taught that God alone is real, and all else borrows its existence from Him. In Daoism and Buddhism the same relationship is expressed as an “emptiness” or “non-being” from which all things come forth.
Either way, trusting God begins with knowing that there’s a spiritual reality behind the reality of things we can see, hear, touch, taste, and smell.
